3. in radiology, a measure of the amount of ionizing radiation at the surface of the irradiated object, such as a person's body; calculated by multiplying milliamperage times exposure time in seconds, expressed in units of milliampere seconds (mAs). See also x-rays. x-ray exposure see exp...

essentially social or crime prevention. In addition, there are pressures arising from medical consumerism and asymptomatic exposures. These are not without implications, and may be less socially acceptable than a bona fide radiology for the patient benefit. Ultimately, they may put themedical exposure...
Exposure creep is the gradual increase in x-ray exposures over time that results in increased radiation dose to the patient. It has been theorized as being... DJ Gibson,RA Davidson - 《Academic Radiology》 被引量: 53发表: 2012年 Computed radiography X-ray exposure trends Rationale and Objecti...
Adjusting Milliamperage or Exposure Time 100mA×0.1s=10mAs To increase the mAs to 20, you could use: 100mA×0.2s=20mAs 200mA×0.1s=20mAs As demonstrated in Math Application 10-1, mAs can be doubled by doubling the milliamperage or doubling the exposure time. A change in either milli...
